faults due to hurricane sandy

1st fault: "water"
2nd fault: "water"
3rd fault: "everywhere"

...and not a drop to drink!

 

I can't help you with the fault codes, but I can save you some money, if you haven't done so already, make sure that there is no water leaked in to the rearends, transmission, and engine. If you just crack the drain plugs the water should come out first, if water has entered the cavities. You might also make sure that no water has entered the airbrake system as well.

 

would you be willing to say your "sunk"

This might help with the fault codes, I didn't know any of the information for your tractor, just click this link.

 

Basically draw a horizontal line at the same height the water got all around the truck. Any electronic module below that line needs to be replaced. Any electrical connection below that line needs to be disconnected, moisture blown out, pack with dielectric grease and reconnect.

 

fuel pressure issues

 

check engine ecm for flood, if sugest water damage remove it, remove cover and let dry.

But fuel pressure sensor is located on filter unit, so lower the ECM

 

the last time I worked on flood damaged volvos was after disaster flood in Europe. I used to repaer damaged in Chech republic trucks.

first of all there were many air system components damaged, like EBS modulators, air dryer, rusty calipers.

Engine ECM is located not so low, but ABS and EBS units are on frame. Frame wiring was wet and there was much sand that damaged wires in a year. so wahs the frame carefully.

change oil in diffs and take front hubs apart to clear with diesel ore kerosine and regrease.

really do not delay this deal, as soon you do it you save more

Disconnect all connectors one by one and use compressed air to clean, put some connector spray (WD40 may be used too) on terminals.
